Abstract

L'invention concerne un dispositif de projection stéréoscopique, comprenant : au moins une source de lumière (2) ; au moins un moyen de collimation (3, 12, 14, 16) servant à convertir la lumière visible (6), que la source de lumière (2) a générée, en une lumière (7) dont la trajectoire des rayons est essentiellement parallèle ; et au moins un filtre d'interférences (10, 11) qui, à un angle d'incidence donné, est transparent pour au moins un intervalle de longueur d'onde avec une largeur d'intervalle d'au plus 50 nm et qui est mis au point pour croiser la lumière (7) avec la trajectoire des rayons essentiellement parallèle.
